no not really
OpenStudy (anonymous):
ok A ratio is simply a comparison between two numbers, or a relationship between two quantities.
Ratios can be expressed in several ways: fraction, decimal, percent, or written with ":" or "to".
OpenStudy (anonymous):
Let's use an example to showcase the different forms:
Suppose there are 4 kids, 3 boys and 1 girl:
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
3:1 (3 boys for every 1 girl)
3/4 are boys, 1/4 are girls
0.75 are boys (divide 3 by 4)
75% are boys (change 0.75 to a percent)

u can write ratios in these forms (above)
OpenStudy (anonymous):
When writing ratios, be sure to use the proper order:
If you write a fraction, the numerator is the quantity you are interested in, and the denominator is the total number of items. This fraction can then be changed to a decimal or a percent.
If you write a comparison, you only use the number of each items, not the total number.
